Karla is a playable character in Fire Emblem: The Blazing Blade. She is the emotionally distant, naive and cool-natured sister of Karel, known as the Princess of Swords. Although she has mastered the art of swordplay, she generally dislikes fighting and often finds peaceful methods of resolving conflict, fighting in arenas mainly in hopes of finding her brother. Still, due to not being influenced by the various other tribes, leading to an ignorant outlook of the world, and even after she finds out the truth about Karel, she strives to redeem him, or die trying. It is implied in her supports with Farina that she and Karel were either born or have lived in Sacae, though she mentioned that her ancestors sailed from across the seas. She and her brother were raised in a place with no contact with the other Sacaen tribes, a place where women are not allowed to touch swords and have to always listen to what men say. With the law of inheritance meant only one would learn the secret ways of the family, she lost everyone in her family except Karel, who then severed ties to his past. She then wandered the continent in search of her brother. While searching for her brother’s whereabouts, she would drop by various arenas, winning in succession until she came to be feared as the “Sword Princess.” In the arena she was challenged by Bartre, who she took interest in and they eventually grew to be lovers. She later marries him and becomes the mother of Fir, but dies of illness a few years before the Fire Emblem: The Binding Blade.
